Certain domestic wastes exhibit characteristics that render them dangerous, such as explosiveness, flammability, spontaneous combustion, reactivity, toxicity and corrosiveness. The lack of information about their generation and composition hinders the creation of special programs for their collection and treatment, making these wastes a potential threat to human health and the environment. We attempted to quantify the levels of hazardous household waste (HHW) generated in Mexicali, Mexico. The analysis considered three socioeconomic strata and eight categories. The sampling was undertaken on a house-by-house basis, and hypothesis testing was based on differences between two proportions for each of the eight categories. In this study, HHW comprised 3.49% of the total generated waste, which exceeded that reported in previous studies in Mexico. The greatest quantity of HHW was generated by the middle stratum; in the upper stratum, most packages were discarded with their contents remaining. Cleaning products represent 45.86% of the HHW generated. Statistical differences were not observed for only two categories among the three social strata. The scarcity of studies on HHW generation limits direct comparisons. Any decrease in waste generation within the middle social stratum will have a large effect on the total amount of waste generated, and decrease their impact on environmental and human health.
某些家庭废物具有危险特性，例如爆炸性、可燃性、自燃性、反应性、毒性和腐蚀性。由于缺乏有关其产生和组成的信息，难以制定专门的收集和处理方案，这些废物对人类健康和环境构成潜在威胁。我们试图量化墨西哥墨西卡利产生的危险家庭废物 (HHW) 的水平。该分析考虑了三个社会经济阶层和八个类别。采用逐户抽样方法，对每个八个类别的两个比例之间的差异进行假设检验。在这项研究中，HHW 占总产生废物的 3.49%，超过了墨西哥以前的研究报告。中等阶层产生的 HHW 最多；在上层阶层，大多数包装都被丢弃，而其中的物品仍然存在。清洁产品占产生的 HHW 的 45.86%。在三个社会阶层中，只有两个类别没有观察到统计学差异。关于 HHW 产生的研究很少，限制了直接比较。中等社会阶层的废物产生量减少将对总废物产生量产生重大影响，并减少其对环境和人类健康的影响。
